I was helping a retired Cummins turbo engineer move a couple years back and he was on the turbo test team, he gave me one, he had a whole box. I wished I'd taken more lol just don't see them around much.
I wish I had taken the boxes of Citgo and Jenney signage my grandfather had from his service station when they sold it. He had dozens of signs from all sorts of products.
I've been slowly trying to pull together signs of stuff that was shown in this pic of his shop back in the day...
